Currently open on my desktop is this window:
Eileen Jewell – never heard of her, but may be worth seeking out
The Rumble Strips – again, see above
Diplo – part of Major Lazer so again, may at some point cross my radar.
But let’s extrapolate this. Man (A) has, and likes, music by Pet Shop Boys ergo he may well like Ain’t No Doubt by Jimmy Nail. I do not think so.
